Here we report the first and most robust evidence about how sleep habits are
associated with regional brain grey matter volumes and school grade average in
early adolescence. Shorter time in bed during weekdays, and later weekend
sleeping hours correlate with smaller brain grey matter volumes in frontal,
anterior cingulate, and precuneus cortex regions. Poor school grade average
associates with later weekend bedtime and smaller grey matter volumes in medial
brain regions. The medial prefrontal – anterior cingulate cortex appears most
tightly related to the adolescents’ variations in sleep habits, as its volume
correlates inversely with both weekend bedtime and wake up time, and also with
poor school performance. These findings suggest that sleep habits, notably during
the weekends, have an alarming link with both the structure of the adolescent
brain and school performance, and thus highlight the need for informed
interventions.
